MATTER
Name the phases of matter?
Liquid,Solid,Gas
Explain the make up of an atom
It is composed of protons, neutrons, and electrons.
Name the symbol for the element with atomic number 1.
The symbol for the element with atomic number 1 is H, which stands for hydrogen.
Explain ionic bonding?
lonic bonding is a type of chemical bonding where electrons are transferred between atoms.
Explain how Covalent bonds are formed.
Covalent bonds are formed when atoms share electrons to achieve a stable electron configuration.
Name the major properties of matter?
There are two major properties:
The two major properties of matter are called Chemical properties, physical properties.
Explain an isotope.
An isotope is an atom of the same protons with a different number of neutrons.
Name the lightest element on the periodic table
Hydrogen (H) is the lightest element on the periodic table.
Explain how cations are formed
Cations are formed when an atom loses one or more electrons, resulting in a positive charge.
Describe a molecule?
A molecule is a group of atoms held together by covalent bonds.
Explain the difference between an element and a compound?
Compounds are made up of two or more elements chemically combined, whereas elements are pure substances that cannot be broken down.
Explain an atomic number
The atomic number of an atom represents the number of protons in its nucleus. It determines the element to which the atom belongs.
The most reactive group of elements on the periodic table.
What is Group 1?
Explain how anions are formed
Anions are formed when an atom gains one or more electrons, resulting in a negative charge.
Covalent bonds are stronger or weaker than ionic bonds.
Covalent bonds are generally stronger than ionic bonds
Explain the difference between a physical change and a chemical change.
Physical changes involve the change in matter's form or state, while chemical changes alter the substance's properties by forming a new substance.
A shell of electrons is a level or orbit of energy around the nucleus where electrons are located.
What is an Electron or Energy Shell?
Name the family that Silicon (Si) is in.
The element is called metalloid.
ionic bonds are either strong or weak bonds.
lonic bonds are generally strong bonds
Name what covalent compounds are usually found as: solid, liquid, or gas at room temperature.
Covalent compounds can exist in any state at room temperature, depending on the specific compound. For example, water is a liquid, while carbon dioxide is a gas.
Explain the Law of Conservation of Mass.
A chemical reaction does not create or destroy mass or matter. A reaction produces a product with a mass that is equal to the total mass of the reactants.
Electrons and protons in an atom are equal, meaning they are electrically neutral. Ions, on the other hand, are atoms that have gained or lost electrons and therefore have positive or negative charges.
What is the difference between an atom and an ion?
Explain the Octet Rule
The overall charge of an ionic compound.
The overall charge of an ionic compound is neutral, as the positive and negative charges of the ions balance each other out.
Name the difference between a single, double, and triple covalent bond.
A single covalent bond involves the sharing of one pair of electrons, a double covalent bond involves the sharing of two pairs of electrons, and a triple covalent bond involves the sharing of three pairs of electrons.
